Description

The LoRa ESP32 with OLED Development Board (SX1276) Heltec – 868Mhz is an all-in-one WiFi plus LoRa Development board that allows you to create LoRa and WiFi projects for internet connected projects like IoT applications. This board is based on ESP32 core chip and a LoRa chip tuned at 868Mhz (SX1276) and the board is based and manufactured by Heltec.

This is a Heltec WiFi LoRa 32 V2 with ESP32 chip board with 8 MB Flash. It integrates a SemTech SX1276 (868Mhz) LoRaWAN communication chip and and an SSD1306 0.96-inch 128×64 OLED display connected via I2C. It has Wi-Fi, BLE, LoRa functions, also Li-Po battery management system. It’s the best choice for smart cities, smart farms, smart home, and IoT makers.

Note: The header pins comes un-soldered, let us know if you want these to be soldered on your board.
